docs(pi): unify split package trees; move live OMP pages to core

Browse Source 
Two directories documented one concept (pi npm packages): top-level
packages/ (browser-use, permission-system) and pi/packages/ (peon,
web-access, subagents). Merged into pi/packages/ — one row per package
in a single index, detail pages kept as archive records. The root
index's 'OMP packages and skills' section was doubly wrong (packages/
was pi, not OMP); it becomes a Skills tooling section pointing at the
consolidated /skills/ tree.

Moved the two LIVE omp pages out of the retired-harness banner:
pi/statusline.md -> core/statusline.md, pi/subagent-limits.md ->
core/subagent-limits.md (both document omp behavior against
agent/config.yml + the installed bundle; pi/index.md itself admitted
the mis-shelf). Retargeted every inbound link (core/index, system/
dankserver, log x2, pi/index, settings x2, moved files' own xrefs).

# OMP Status Line Customization
Ground truth from the installed bundle (`@oh-my-pi/pi-coding-agent/dist/cli.js`),
verified live on blankpad 2026-10-18 and re-audited line-by-line against the
minified source the same day (see [Audit log](#audit-log)). Status knobs live
in `agent/config.yml` under `statusLine:`; the two composer knobs
(`composer.shape`, `composer.tokenRate`) under `composer:`. The file is
file-watched — edits repaint a running session without restart (verify
visually: niri screenshot, see [niri capture recipe](../system/index.md)).
`/settings` (Appearance tab) previews these live with sample data.
## Preset vs custom — the trap
`statusLine.preset` ships whole configurations. **`leftSegments` /
`rightSegments` are ignored unless `preset: custom`** (`s ? user ?? preset
: preset` in the resolver). **`segmentOptions` is NOT gated** — user options
merge over the preset's own options under *every* preset.
| preset | leftSegments | rightSegments | separator |
|---|---|---|---|
| `default` | pi vim model mode collab stream path git pr context_pct cost | session_name | powerline-thin |
| `minimal` | vim path git | session_name mode context_pct | slash |
| `compact` | vim model mode git pr | session_name cost context_pct | powerline-thin |
| `full` | pi vim hostname model mode path git pr subagents | session_name cache_hit token_in token_out token_rate cache_read cost context_pct time_spent time | powerline |
| `nerd` | pi vim hostname model mode path git pr session subagents | session_name token_in token_out cache_read cache_write token_rate cost context_pct context_total time_spent time | powerline |
| `ascii` | vim model mode path git pr | session_name token_total cost context_pct | ascii |
| `custom` | your `statusLine.leftSegments` | your `statusLine.rightSegments` | powerline-thin |
The built-in default for `statusLine.leftSegments`/`rightSegments` themselves
is the `ascii`-era pair (`vim model mode path git pr` / `session_name
token_total cost context_pct`) — a config carrying those arrays with a named
preset is running the preset, not the arrays. The fleet runs `preset: custom`.
## Composer shape routes the segments
`composer.shape` decides *where* the two arrays render. Eight shapes ship in
the bundle; the plugin API can register more (`zG()` = built-ins + a live
registration map). Internally each shape carries `statusAttachment`,
`bottomBar`, `bottomBarGap`:
| shape | attach | bottom bar | leftSegments | rightSegments |
|---|---|---|---|---|
| `band` (fleet, default) | top-band | none | merged single row above editor, left | same row, right (`session_name` skipped — title rides the working row) |
| `box` | top-border | none | box top border | box top border |
| `claude` | top-rule-chip | left | bottom strip, left | top rule chip, right-aligned |
| `rule` | top-rule-chip | left + gap | like claude, gap above strip | like claude |
| `pi` | none | full | single bottom bar | single bottom bar |
| `borderless` | none | full | single bottom bar | single bottom bar |
| `field` / `rail` | none | full + gap (filled surface) | single bottom bar | single bottom bar |
The chip/strip layouts paint their rules as **session-accent fillers, not
meters** — the context meter exists only in `box` and `band`
(see next section). The top-rule chip renders right segments only, the bottom
strip left segments only.
The working row is composer chrome, not segment-addressable: session title +
shimmer, plus the tok/s readout when `composer.tokenRate: true` (default
false). The readout is estimated from streamed deltas, corrected by billed
output counts; the bundle also mentions a native-composer-bar placement in
filled styles.
## The context meter
`statusLine.contextLine` (enum `off` / `percentage` / `annotated` /
`embedded`, default `embedded`) tunes the rule between the segment groups.
The knob description says "box composer only" — **that is wrong**: the meter
renders in `box` **and** `band`; in every other shape the rule is a constant
session-accent filler regardless of this setting (live-verified claude with
`off` vs `embedded`: identical, and not context-proportional).
In box/band:
- `off` → plain accent rule (single color, full width).
- `embedded` → the inline labeled meter: `60% ——— × 200K`. Requires
`contextWindow > 0`, a `context_pct`/`context_total` segment present in
either array, and at least one non-context segment. The context segment(s)
are **hoisted out of the arrays** — they never render as text in this mode.
- `percentage` / `annotated` → unlabeled proportional meter painted into the
rule (live-verified in band: colored fill ∝ usage at the rule's right end);
`context_pct` stays a normal text segment.
Fill length ∝ `min(100, contextPercent)`; >100% paints the raw percent and
shortens the meter. Meter/segment color thresholds scale with window size —
warning at ≥ min(50 %, 150K tokens), purple ≥ min(70 %, 270K), error ≥
min(90 %, 500K); below that the theme's `statusLineContext` color.
## Segment universe (27)
`pi`, `status`, `model`, `mode`, `path`, `git`, `pr`, `subagents`,
`token_in`, `token_out`, `token_total`, `token_rate`, `cost`, `context_pct`,
`context_total`, `time_spent`, `time`, `session`, `hostname`, `cache_read`,
`cache_write`, `cache_hit`, `session_name`, `usage`, `collab`, `stream`, `vim`.
Zero/inactive segments render nothing — dead weight costs no width.
| segment | renders | trigger / notes |
|---|---|---|
| `pi` | brand glyph + turn-elapsed | while streaming; focused-agent ghost id (warning color) when a subagent is focused |
| `status` | hook/extension statuses, dot-joined | extension pushes via `ctx.ui.setStatus()` (ordered by key); suppressed in footer when `statusLine.showHookStatus: false` |
| `model` | display `name` + thinking level | suffix hidden by `segmentOptions.model.showThinkingLevel: false`; `statusLine.compactThinkingLevel: true` (default) swaps in a compact glyph; fast-mode, advisor/tariff badges attach here |
| `mode` | `Plan` / `Prewalk` / `Goal` / `Vibe` / `Loop …` | only in those modes (paused variants add a pause glyph); there is **no yolo/auto-approval display** in this segment |
| `path` | cwd or `project/worktree` label | see [Path segment](#path-segment-and-stripworkprefix) |
| `git` | branch + dirty badges | `+N` staged, `*N` unstaged, `?N` untracked (`segmentOptions.git.showStaged/showUnstaged/showUntracked`, default true); `showBranch: false` hides branch text and keeps badges (git icon carries them); color flips on dirty |
| `pr` | `#<number>` hyperlink | only once the session has an associated PR |
| `subagents` | count | hidden at 0; when subagents are actively running the composer paints its own live badge and this segment self-suppresses |
| `token_in` / `token_out` | cumulative session input/output tokens | hidden at 0; `cache_read` / `cache_write` likewise cumulative |
| `token_total` | `input + output + cache_write + orchestration_in + orchestration_out` | hidden at 0 |
| `token_rate` | `N.N tok/s` | hidden when not streaming (the working-row readout is a separate, `composer.tokenRate`-gated thing) |
| `cost` | session cost | includes subagent-tree + advisor cost; `↑`/`↓` peak/off-peak arrow for time-priced providers |
| `context_pct` | `NN.N%/200K` (or window alone when percent is unknown) | hoisted into the meter in `embedded` box/band; auto-compact speculation icon rides along |
| `context_total` | absolute context tokens | also hoisted by the embedded meter |
| `time_spent` | active session time | hidden under 1 s; this is *active* time, not wall clock |
| `time` | wall clock | `segmentOptions.time.format: "12h"/"24h"`, `showSeconds` |
| `session` | first 8 chars of session id (`new` before resume exists) | resume-by-id handle |
| `session_name` | session title, accent | in `band` it renders on the working row instead |
| `hostname` | short hostname | accent-tinted with session color |
| `usage` | rate-limit windows | 5h / daily / 7d / monthly bars + tier badge, when the provider reports them |
| `collab` | `collab:N` / `collab guest:N` | only in collab sessions |
| `stream` | `● LIVE <viewers>` / `● REC` | only while streaming/recording |
| `vim` | mode glyph/word | only while vim keybindings are active; selected-line count appended (` 3L`); `display` icon vs text comes from the vim runtime, not config |
## Path segment and `stripWorkPrefix`
`segmentOptions.path.stripWorkPrefix` (default **true** — the code tests
`!== false`) gates two behaviors in the `path` renderer:
1. **Worktree sessions:** `true` never shows the disk path — it renders the
logical `projectName/worktreeName` label (bare `projectName` when the
current branch is named after the worktree) with the worktree glyph.
`false` opts out and shows the real cwd with a folder glyph, plus a
` ↳ relativeRepoRoot` suffix inside a repo. Base-directory-only is not
renderable in either mode.
2. **All sessions:** `true` uses the pretty display path (scratch sessions
get the scratch-folder icon); `false` uses the raw absolute cwd.
`abbreviate` (default **true**: home → `~`; `false` keeps the full path —
also affects tool labels/errors per upstream docs) and `maxLength` (clip,
default 40) apply afterwards in both modes. The fleet runs `true` — logical
label, worktree glyph (verified live 2026-10-18; an earlier trial of `false`
for the full cwd was rejected by eye).
## Status knobs (registry-verified)
`statusLine.preset` · `.leftSegments` · `.rightSegments` · `.segmentOptions` ·
`.separator` (`powerline` `powerline-thin` `slash` `pipe` `block` `none`
`ascii`; default `powerline-thin`) · `.contextLine` · `.sessionAccent`
(default true; hashes the session name into the editor border *and* the
accent-tinted segments/meter color) · `.transparent` (terminal background,
no status bg fill) · `.showHookStatus` · `.compactThinkingLevel` (default
true). Plus `symbolPreset` at top level (`unicode` `nerd` `ascii` — segment
glyphs follow it).
## Fleet configuration (2026-10-18)
- Shape `band`: one merged status row. Left group: `session_name`→working
row (skipped), `vim`, `mode`, `hostname`, `path`, `git` (no branch text —
worktree branches are autogenerated names), `pr`. Right group (array order
= paint order, so the last entry hugs the screen edge): `model`, `cost`,
`context_pct`, `time_spent` — `context_pct` hoists out of the run to paint
the labeled inline meter (`60% ——— × 200K`) between the groups under
`contextLine: embedded`.
- Deliberately cut: `token_rate` (working-row readout covers it), `time`
(panel clock), `cache_*` (noise), `context_total` (implied by the meter),
`subagents` (live badge supersedes it), `session`, `token_in`/`token_out`
(cumulative totals are in `/session` anyway).
- `models.yml`: frank-archon's display `name` slimmed to `"frank-archon"`
(endpoint suffix dropped); frank-dragoon/frank-zealot keep their endpoint
suffixes. `name:` is free-form display, `id:` is the wiring — renaming ids
is the cutover procedure, see [Pi Models](/pi/models.md).
## Audit log
2026-10-18 full-source re-audit corrected the first pass of this page:
- ~~claude shape's top rule is the context meter~~ — **false**. The
meter code path runs only for `box`/`band`; claude/rule/pi/borderless/
field/rail rules are constant session-accent fillers. (Earlier reading
mistook the accent rule for a meter.)
- ~~working-row composer-bar variant is "Tern-only"~~ — **false**; the
tok/s readout is the `composer.tokenRate` option (default false), title
placement is composer chrome.
- ~~`segmentOptions` gated to `preset: custom`~~ — **false**; options merge
under every preset, only the segment *arrays* are gated.
- ~~`mode` covers yolo~~ — **false**; states are Plan/Prewalk/Goal/Vibe/Loop.
- `contextLine` "(box composer only)" — the *bundle description* is wrong;
band honors it too (verified live: `off` plain rule, `percentage` rule
meter, `embedded` inline meter, screenshots + code).
